The most sustainable thing for me is the 50% rule: Roughly 50% by weight of your daily food intake should be unprocessed fruits and vegetables. There is no science behind this heuristic, but it's a way to a) make sure that you're eating more non-calorie-dense foods, and b) to force you to get creative in how you plan meals. There are undoubtedly more efficient ways, but it works for me because it's easy to stick to long-term.
